Super High Precision Type Thick Film Chip Resistors
Panasonic Industry, a worldwide leader in Resistor Products, introduces the new Super High Precision Thick Film Chip Resistors Series. The new ERJ-PC Series is engineered to bridge the performance gap between conventional thick film and thin film resistors. The ERJ-PC Series delivers a resistance tolerance of ±0.1% and a temperature coefficient of resistance of ±25 ppm/K - comparable to thin-film resistors - while preserving thick-film construction through proprietary materials and process design.
The Thick Film Chip Resistors (Super High Precision Type) Series of Resistors are engineered to meet demanding requirements of industrial, automotive, and high-reliability applications. The ERJ-PC Series provides exceptional stability, combined with superior environmental durability and robust resistance to ESD and corrosion, ensuring long-term performance in harsh operating conditions.
Product Overview and Features
1. High Precision:
Resistance Tolerance: ±0.1%, TCR: ±25 ppm/K
Provides precision performance that exceeds conventional thick-film resistors.
2. High Reliability:
Achieves industry-leading* resistance stability for thick-film resistors (resistance change rate ±0.2% or less in various reliability tests).
Offers superior environmental resistance, including protection against ESD and contamination—common weaknesses in thin-film resistors.
*According to our research as of November 2025
3. High Power Rating:
Achieves higher rated power compared to conventional thin-film products (e.g., 1608 size: 0.1W → 0.2W)
Product Lineup and Specifications
- Sizes: 0402*, 0603, 0805, 1206 (inch)
- Rated Power: 0.20W (0603), 0.25W (0805), 0.40W (1206)
*1005 size is currently under development
Power Comparison with Conventional Thin Film Resistors
By substituting thin-film resistors with thick-film resistors of the same size, you can achieve higher power handling.
