How does YMIN solid-state capacitors solve the PCB layout challenge of high-density power banks with ultra-thin packaging?

 

Introduction

In current electronic device design, the contradiction between PCB height and wiring density is becoming increasingly prominent. Traditional electrolytic capacitors, due to their bulky size, cannot meet the requirements of compact layouts, especially in multi-layer boards and high-current applications, where their high ESR, short lifespan, and large space occupation become prominent issues.

YMIN Solution and Advantages

YMIN solid-state capacitors achieve a thinner package structure with the same capacitance value by using high-conductivity polymer materials and winding technology. Taking the VP4 series as an example, its 3.95mm height is the thinnest surface-mount capacitor globally, with a rated voltage of 6.3V~35V and an ESR of only 60mΩ under a capacitance of 220μF.

【Case Study 1: Wireless Charging – An Alternative Solution for Ceramic MLCCs】MLCC Specifications: 25V 10μF (0805/0603 package) Solid Capacitor: VPX 25V 100μF 6.3*4.5 (Surface Mount) Advantages of the Alternative Solution: Integrating a large array of MLCCs with a single high-performance electrolytic capacitor, thereby greatly saving PCB area, simplifying design, and improving capacity stability.

Effective Capacity Stable and reliable: Within the rated voltage and temperature range, the capacity retention rate is ≥95%, always providing ~100μF. Severe and unpredictable attenuation: The effective capacity changes greatly with voltage and temperature, and the actual total capacity of 10 MLCCs may still be insufficient. Provide stable and predictable performance, with smaller design margin and more stable system.
Occupied Area Small: Only one component position is needed (6.3mm x 4.5mm). Very large: 10-20 component positions (e.g., 0805/1206 packaging requires a huge area). Free up PCB space, allowing for more compact layout or freeing up space for other important signal wiring.
Mechanical Reliability High: Solid-state structure, no risk of bending or cracking. Low: Ceramic material, PCB is prone to cracking under bending force, leading to failure. Improve productivity and product life, especially suitable for large-sized or potentially bent boards.
Audible Noise No piezoelectric effect, completely silent. Piezoelectric effect may cause audible high-frequency squeal. It is a decisive advantage for audio circuits or devices pursuing silence.
Comprehensive Application Cost Low cost, stable performance, no need to design complex compensation circuits for capacity attenuation. High cost, need to reserve design margin for capacity instability. Better price and more stable and reliable performance.
