II. Product Categories and Series

EVER OHMS is one of the few manufacturers with capabilities across thick film, thin film, and metal plate resistor technologies.

1. Thick Film Resistors

CR Series: Standard thick film chip resistors covering 0201 to 2512 package sizes.

CRH Series: High-power thick film chip resistors. Taking CRH2512 as an example, it achieves 2W power rating in standard 2512 package—typically 1W for conventional products—through ceramic substrate thermal optimization and resistive paste formulation improvements. Typical model: CRH2512F5R60E04Z (2512 5.6R 2W) .

CUH Series: Optimized for high-temperature environments.

CHH Series: High-power thick film resistors, with 2512 package achieving 4W power rating.

HV/HVR/HVL Series: High-voltage thick film resistors for power modules and high-voltage test equipment.

2. Thin Film Resistors

Mass production began in 2003. In Q3 2025, thin film resistors accounted for 40% of total revenue.

TR Series: Precision thin film resistors with accuracy up to ±0.1% and TCR as low as ±15ppm/℃.

TRL/TGL Series: Metal film chip resistors with high precision and surge withstand capability.

3. Metal Plate (Alloy) Resistors

MA Series: Ultra-low resistance (down to 0.3mΩ), high power (up to 7W) alloy resistors for new energy vehicle BMS and industrial inverters.

MR Series: Cost-effective solution for consumer electronics power management.

MRE Series: Compact package (0201 to 1206) for space-constrained devices.

MU Series: Optimized for ultra-low resistance and high-frequency switching environments.

4. Current Sensing Resistors (4-Terminal)

ERS/ERL/ERM Series: Four-terminal current sensing resistors eliminating lead resistance impact on measurement accuracy.

5. Anti-Sulfuration Resistors

ST/STH Series: Designed for harsh industrial environments with sulfur corrosion resistance.

6. Automotive-Grade Resistors

QR Series: AEC-Q200 compliant for automotive electronics.

7. Resistor Arrays

Chip resistor arrays available in 0603x4, 1206x4, 0402x4 packages.

III. Market Applications

Application breakdown: Power supplies 35% (largest segment), Industrial electronics 25%, Automotive electronics 18%, Consumer electronics 10%, AI applications 6%.

1. Power Management

Thick film resistors, metal plate resistors, and metal plate shunts are used in AI power modules for major power supply manufacturers.

2. AI Servers

EVER OHMS has entered the GB200/GB300 supply chain. AI servers require 3x more resistors than general servers (15-30 vs 5-10). AI revenue share grew from 3% (2024) to 6% (2025), targeting 8-10% in 2026.

3. Automotive Electronics

Automotive-grade and alloy shunt resistors are widely used in BMS, motor controllers, infotainment systems, and airbag control units.

4. Industrial Automation & Power Equipment

High-power, surge-resistant, and high-voltage resistors used in servo drives, inverters, PLC modules, and power protection circuits.

5. Communications & Consumer Electronics

5G base stations, smartphones, laptops, and fast chargers.

6. High-End Instruments & Medical Equipment

Precision thin film resistors for test instruments, medical devices, and aerospace applications.

V. Summary

Since 1988, EVER OHMS has grown from a chip resistor manufacturer to a listed company spanning thick film, thin film, and metal plate technologies. The company maintains technological leadership in high-precision thin film resistors and low-resistance, low-TCR, high-power-density alloy current sensing resistors. In May 2026, monthly revenue reached NT$190 million, up 58.67% year-over-year, marking three consecutive months of record-high monthly revenue.

For resistor selection and procurement, it is recommended to source through authorized channels such as Shenzhen Shunhai Technology or Huanian Mall to ensure genuine products and professional technical support.
