As a power supply engineer, have you repeatedly encountered the following scenarios when debugging PD fast charging adapters or power bank prototypes? Capacitor overheating under full load, persistently high standby power consumption, insufficient PCB space, and a persistently inadequate filtering capacity.
This article will take YMIN’s VPX/VPT/VP4/NPX series high-capacity-density solid-state capacitors as examples, combining detailed test data and typical cases to conduct an in-depth technical analysis, showing how it systematically solves these design pain points.
Ultra-Low ESR
Eliminating the “Culprit of Overheating”: Optimizing Temperature Rise Through Data
Root Cause of Pain Point: Taking a 65W GaN PD fast charging adapter as an example, if a common solid-state capacitor with an ESR of 40mΩ is used to carry a 2A ripple current, the loss per capacitor reaches 0.16W, leading to a core temperature exceeding 85℃ in a confined space.
YMIN Solution: High-conductivity polymers and optimized electrode structure reduce ion migration resistance.
Real-world testing data: YMIN VPX series ESR as low as 20mΩ@100kHz. Under the same conditions, power loss is reduced to 0.08W, and heat generation is halved. Test data before and after reflow soldering shows that the overall ESR change rate is controlled within 15%, demonstrating excellent thermal stability.
Design value: Provides a solution for fundamentally “cooling” high-power-density power supplies, directly improving system efficiency and long-term reliability.
Ultra-Low Leakage Current
Overcoming “Static Power Consumption,” Validating Standby Optimization with Data
Root Cause of Pain: In portable devices, even when the main control IC enters sleep mode, capacitor leakage current continues to consume battery energy.
YMIN Solution: A dual-track process of “special electrolyte + precision formation” forms a dense oxide layer, suppressing carrier migration.
Measured Data: Taking the VPX 25V 100μF specification as an example, the standard specifies a leakage current ≤5.0μA. YMIN conducted pre- and post-reflow soldering tests on 10 samples. The average leakage current before soldering was 1.002μA, and after soldering it was 2.329μA. The maximum value (3.050μA) is still far below the standard upper limit (≤10μA) and the industry average (≤25μA).
Design Value: For devices requiring continuous standby, YMIN capacitors effectively curb “hidden power consumption,” providing a measurable and verifiable solution for improving battery life.
Application Case: Anker 10000mA 30W Fast Charging Automatic Power Bank
The Anker 10000mAh power bank with a built-in cable features a single YMIN VPX series 25V 100UF 6.3*5.8 low-leakage solid-state capacitor. This capacitor addresses the following pain points:
1. Significantly extended standby time: Effectively reduces static power consumption, enabling power banks and similar products to truly achieve “ready to use anytime, long-lasting power”;
2. Improved system reliability: Excellent post-reflow soldering characteristics ensure consistency and stability in mass production, reducing after-sales risks;
3. Enhanced product competitiveness: Ultra-low leakage current is a direct selling point for the device’s long battery life, especially suitable for high-end power banks.
Thinner Design
Solving the “Space Conflict”: A Case Study Demonstrating Layout Innovation
Root Cause of Pain Point: The conflict between PCB layout height and wiring density intensifies, and traditional electrolytic capacitors and MLCC arrays occupy too much space.
YMIN Solution: The world’s thinnest VP4 series (3.95mm), providing an innovative solution that “replaces an entire MLCC cluster with a single capacitor.”
Application Case: Anker 14-in-1 Display Desktop Charging Dock
This solution has been successfully applied to products such as the Anker 14-in-1 desktop charging dock, providing crucial space support for its high-density interconnectivity and complex functionality. It integrates two YMIN VPX 25V 220μF 6.3*5.8mm surface-mount solid-state capacitors and two VPX 25V 100μF 6.3*4.5mm surface-mount capacitors. Taking the commonly used 100μF/25V specification as an example, it addresses the following pain points:
The YMIN VPX capacitor measures only Φ6.3×4.5mm, reducing its volume by 22% and height by 1.3mm compared to traditional capacitors (Φ6.3×5.8mm); space utilization is improved by nearly 30%, freeing up crucial space for battery expansion or adding functional modules; achieving superior layout flexibility and signal integrity.
Application Advantages
YMIN’s ultra-thin solid-state capacitors significantly improve space utilization and system performance in high-density designs. YMIN’s ultra-thin solid-state capacitors deliver measurable improvements to compact electronic devices, providing an ideal solution for achieving both high performance and extremely small size. This includes:
1. Freeing up design space: Enabling more complex routing, additional functional circuitry, or improved heat dissipation solutions.
2. Enhancing performance options: The freed-up space can be used to improve overall system performance, reliability, or add new features.
High Capacity Density
Breaking Through “Size Limitations,” Achieving Power Leap Through Parameters
Root Cause of Pain: The contradiction between device miniaturization and high-performance requirements; traditional capacitors cannot provide sufficient filtering capacity within limited space.
YMIN Solution: Nanoscale high-voltage anode foil technology, increasing capacity per unit volume.
Parameter Comparison:
VPX/VPT 25V 220μF: Size 6.3*5.8mm, while competitors’ products of the same specification are mostly 6.3*7.7mm.
NPX 25V 470μF: Size 5.5*12mm, while competitors’ products of the same capacity are mostly 6.3*15mm.
End-User Verification: In products such as the Lenovo Legion PB9 gaming laptop fast-charging power bank (using the VPX series) and the FlashPower 170W Cyber Prism power bank (using the VPX & VP4 series), YMIN’s high-capacity-density solid-state capacitors are key to achieving high power output and stable performance within a compact space.
Application examples: Lenovo Legion PB9 gaming laptop fast charging power bank, FlashGet 170W Cyber Prism power bank
The Legion PB9 gaming laptop fast charging power bank has three built-in YMIN VPX 35V 100μF 6.3*5.8 solid capacitors, one YMIN VPX 25V 220μF 6.3*5.8 solid capacitor, and six YMIN VPX 35V 47μF 6.3*4.5 solid capacitors.
The FlashPower 170W Cyber Prism power bank incorporates seven YMIN VPX 35V 100μF 6.3*5.8 solid-state capacitors, one YMIN VPX 25V 220μF 6.3*5.8 solid-state capacitor, and two YMIN VP4 35V 47μF 6.3*3.95 solid-state capacitors.
The application of these YMIN capacitors addresses the following pain points:
1. Core Advantage: Improved Space Utilization: Compact size frees up valuable layout space, allowing for more design margin for batteries, heat dissipation modules, or other critical components.
2. Enhanced Electrical Performance: High capacity density effectively optimizes filtering and energy storage, improving system voltage stability, especially meeting the stringent requirements of fast charging and high-speed circuits.
3. Optimized Overall Cost: Reduces the number of capacitors connected in parallel, simplifies the BOM list, and lowers material and management costs.
