Demand for high precision and low TCR is growing across automotive, industrial equipment, and data server applications. The ERJPC Series achieves high precision comparable to conventional thin-film resistors in a thick-film chip resistor. It solves environmental resistance and power performance challenges all at once.
Product Overview and Features
The ERJPC Series achieves resistance tolerance (±0.1%) and temperature coefficient of resistance (±25 ppm/K) equivalent to thin-film resistors, while maintaining thick-film construction through proprietary materials and process design.
- High Precision:
- Resistance Tolerance: ±0.1%, TCR: ±25 ppm/K
- Provides precision performance that exceeds conventional thick-film resistors.
- 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
- 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 replacing thin film resistors with thick film resistors of the same size, higher power handling can be achieved.
