ERJPC High Precision Thick Film Chip Resistor (Super High Precision Type)

Demand for high precision and low TCR is growing across automotive, industrial equipment, and data server applications. The ERJPC High Precision Thick Film Chip Resistor series achieves high precision comparable to conventional thin-film resistors in a thick-film chip resistor construction. It solves environmental resistance and power performance challenges all at once.

The ERJPC High Precision Thick Film Chip Resistor 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., 0603 size: 0.1W →0.2W)

Compared with thin film resistors of the same size, the new ERJPC High Precision Thick Film Chip Resistor (ERJPC) provide higher power capability, allowing the same power rating to be achieved in a smaller case size. ERJPC series enables up to 50% PCB space saving, supporting overall board miniaturization.
