In today’s pursuit of device miniaturization, a single capacitor can be the key to a product’s success or failure.
In the field of electronic device design, power supply engineers often face dilemmas such as: capacitors overheating under full load, high standby power consumption, insufficient PCB space, and seemingly inadequate filtering capacity. These seemingly minor issues can directly impact product performance and reliability.
Shanghai YMIN Electronics’ polymer solid-state capacitor solutions, with their four core advantages—ultra-low ESR, ultra-low leakage current, thin profile, and high capacitance density—are becoming the preferred choice for many well-known brands.
01 Ultra-Thin Design Solves Space Constraints
The YMIN VP4 series solid-state capacitors are only 3.95 mm thick, providing the industry with an ultra-thin solution. This breakthrough size allows the capacitors to thrive in space-constrained applications such as power banks and fast charging adapters.
Compared to traditional capacitors, the YMIN VPX series measures Φ6.3×4.5 mm, reducing volume by 22% and height by 1.3 mm, improving space utilization by nearly 30%.
The Anker 14-in-1 Display Desktop Charging Dock fully leverages this advantage, incorporating multiple YMIN thin capacitors to achieve a dense layout of 14 ports within a limited space.
02 Ultra-Low ESR Eliminates Overheating Issues
High temperatures are the “invisible killer” of electronic components. YMIN solid-state capacitors utilize high-conductivity polymers and optimized electrode structures to reduce the ESR value to 20mΩ@100kHz.
Real-world testing data shows that in a 65W GaN PD fast charging adapter, YMIN capacitors reduce power loss from 0.16W to 0.08W, directly halving heat generation and keeping the core temperature below 85℃.
This characteristic is particularly important for high-power applications such as AI servers. The YMIN MPS series can achieve an ESR as low as ≤3mΩ, meeting nanosecond-level transient response requirements.
03 Ultra-Low Leakage Current Extends Standby Time
In portable devices, even when the main control IC enters sleep mode, capacitor leakage current continues to consume battery energy. YMIN utilizes a dual-track process of “special electrolyte + precision formation” to form a dense oxide layer, effectively suppressing carrier migration.
Taking the VPX 25V 100μF specification as an example, the standard specifies a leakage current ≤5.0μA, while YMIN’s samples, after reflow soldering, have an average leakage current of only 2.329μA, far below the industry standard of 25μA.
Anker’s 10000mAh 30W fast charging power bank leverages this characteristic to significantly extend standby time, achieving a user experience of “readily available and long-lasting power.”
04 High Capacity Density Enhances Power Output
The problem of traditional capacitors being unable to provide sufficient filtering capacity in limited space has been solved by YMIN’s nano-level high-voltage anode foil technology. Its VPX/VPT 25V 220μF capacitor has a size of 6.35.8mm, while most competitors’ products of the same specification are 6.37.7mm.
The FlashGet 170W Cyber Prism power bank achieves high power output within a compact space, utilizing seven YMIN VPX 35V 100μF capacitors and two VP4 series capacitors.
This feature allows product designers to achieve higher power density and more stable performance output without increasing size.
YMIN solid-state capacitors have gained favor with many well-known brands. Whether it’s the Lenovo Legion gaming laptop fast-charging power bank or the FlashGet 170W Cyber Prism power bank, both rely on YMIN capacitors to ensure stable performance.
Choosing YMIN is not just choosing a reliable component, but also choosing a strategic partner that can help your product achieve breakthroughs in efficiency, battery life, size, and reliability.
