Automotive-Grade Capacitors & Domestic Substitution | Shanghai Yongming Showcases Capacitor Solutions for Four Major Sectors at PCIM Asia 2026: New Energy Vehicle Electronics

PART 01 Introduction

Shanghai Yongming Electronics will participate in the 2026 Shenzhen International Power Components and Renewable Energy Management Exhibition & Conference from August 26 to 28, located at Booth D28, Hall 16 of the Shenzhen World Exhibition & Convention Center (Bao’an New Venue). Yongming will comprehensively showcase its capacitor solutions across four core sectors—New Energy Vehicle (NEV) electronics, AI servers, drones & robotics (motor drives), and energy & industrial power—while exploring how technological innovation in core components drives industrial upgrading.

In the NEV electronics sector, Yongming’s capacitor solutions cover key applications such as thermal management systems, safety systems, electric drive and control units, Crash Protection Modules (CPM), smart cockpits, and lithium-ion battery management systems (BMS) for parking power supplies. Its entire product line is AEC-Q200 certified. From electric drives to cockpits, and from thermal management to safety systems, Yongming offers OEMs and Tier 1 suppliers domestic alternatives capable of pin-to-pin replacement for imported brands.

PART 02: Comprehensive Automotive Scenario Coverage & Automotive-Grade Certification – Yongming’s Capacitor Solutions for New Energy Vehicle Electronics

1) Thermal Management System – Electronic Water Pumps: Conductive Polymer Hybrid Capacitors (150°C Wide Temperature Range + 30G Vibration Resistance)

Automotive electronic water pumps face multiple challenges during operation, including high vibration, wide-range thermal shock, and high ripple currents. To address these complex operating conditions, Yongming offers three series of conductive polymer hybrid capacitor solutions—VHT, VHU, and VHR—featuring the following core advantages:

High-Vibration-Resistant Structural Design: Standard products withstand 10G vibration, with vibration resistance reaching up to 30G when equipped with a mounting base.

Dual-Electrolyte Technology: The VHT, VHU, and VHR series collectively form a product matrix covering the full temperature spectrum from 105°C and 135°C up to 150°C.

Ultra-Low ESR and Wide-Frequency Stability: ESR values ​​as low as 0.020Ω (at 100kHz) and the ability to handle high ripple currents up to 2800mA (at 125°C) ensure smooth and stable output current.

Real-World Case Study: In an electronic water pump application for a new energy vehicle, the VHU series (25V, 470μF, 10×10.5) hybrid capacitor solution was selected. It successfully eliminated abnormal noise during cold starts and passed 10G vibration testing. The solution demonstrated minimal electrical performance fluctuation across the full -55°C to 125°C temperature range, achieving a successful domestic replacement for Japanese brands.

2) CPM Crash Power Module: A supercapacitor-based solution (replacing batteries) offering millisecond-level response.

Emergencies such as electronic door lock failures in new energy vehicles have created a need for CPM crash power modules, specifically requiring instantaneous activation capabilities. Yongming’s SDH series supercapacitors replace traditional batteries and are designed to handle extreme conditions—including power loss during crashes, short circuits due to water immersion, and low-power operation in extreme cold (-40°C). They translate “energy storage parameters” into “guaranteed operational reliability following a crash or power loss,” ensuring at least one reliable emergency unlock after an accident. This eliminates the risk of safety lockouts and provides robust redundancy for vehicle safety systems.

Low ESR: Delivers stable, high-current output—instantly providing hundreds of amperes—to ensure reliable door lock operation after a crash. Low leakage current ensures availability after long periods of standby, while high consistency and traceability guarantee the reliable implementation of multi-cell modules.

Wide Temperature Performance: Operates between -40°C and 85°C with <10% capacity degradation and <15% ESR variation; maintenance-free throughout its entire lifecycle.

Ultra-long Lifespan: Cycle life exceeds 500,000 cycles; withstands high temperatures (85°C for 1,000 hours); solutions available for 5, 10, or 15-year lifespans

3) Airbag ECU: LK Series Aluminum Electrolytic Capacitor Solution
Airbag ECUs demand high performance regarding low-temperature discharge, high-temperature lifespan, and overall durability. Yongming’s LK series (liquid-electrolyte, radial-lead aluminum electrolytic capacitors) is AEC-Q200 qualified and serves as a direct, like-for-like replacement for the NCC LBG/LBV series.

Low-temperature, high-rate discharge: At -40°C/120Hz, the ESR of the LK series is as low as 97.72mΩ (offering pin-to-pin compatibility with the NCC LBV series).

High-temperature, long lifespan: After 3,000 hours at 105°C, capacitance degradation is only -2.71%; performance rivals that of Japanese counterparts, allowing for direct replacement.

Durability: A cycle life of 100,000 cycles ensures stable performance during frequent system self-checks.

4) Electric Drive & Control: Film capacitor solutions designed to meet the challenges of 800V high-voltage systems.

These products utilize modified metallized polypropylene film and a multi-tab structure; their ultra-low ESR makes them a perfect match for high-frequency SiC circuits, effectively suppressing voltage spikes and reducing overall system power consumption. Equipped with self-healing protection technology, they ensure safe and reliable operation.

· Non-polarized design with a lifespan exceeding 100,000 hours; fully sealed epoxy encapsulation ensures stable operation in the harsh environments typical of automotive applications.

· Real-world case study: 8 MDP capacitors replaced 22 aluminum electrolytic capacitors, resulting in a PCB footprint reduction of over 50%, a 40% decrease in peak bus voltage, and an approximately 1.5% increase in peak system efficiency.
