MRS10KBF

MRS10KBF Description

The MRS10KBF from TE Connectivity Passive Product is a high-precision 4-resistor network designed for demanding applications requiring tight tolerance and low TCR (Temperature Coefficient of Resistance). Housed in a compact 1206 (3216 Metric) convex package with long-side terminals, this 10kΩ array offers ±0.1% tolerance and ±25ppm/°C TCR, ensuring stable performance across temperature variations. The isolated circuit configuration and 62.5mW power rating per element make it suitable for precision voltage division and signal conditioning. Despite its obsolete status, it remains a reliable choice for legacy designs due to its ROHS3 compliance and REACH-unaffected environmental credentials.

MRS10KBF Features

• Precision Matched Resistors: ±0.1% tolerance and ±25ppm/°C TCR for high-accuracy applications.
• Robust Construction: 1206 package (3.20mm x 1.60mm) with convex, long-side terminals for improved mechanical stability.
• Surface-Mount Design: 0.026" (0.65mm) seated height enables low-profile PCB integration.
• Reliable Performance: 62.5mW power dissipation per resistor and MSL 1 (unlimited) moisture sensitivity.
• Environmental Compliance: ROHS3 and REACH-unaffected, meeting stringent industry standards.

MRS10KBF Applications

• Voltage Dividers: Ideal for TCR-matched precision dividers in instrumentation and sensor interfaces.
• Signal Conditioning: Used in ADC/DAC reference networks and analog front-end circuits.
• Legacy Systems: Suitable for obsolete-design maintenance where consistent performance is critical.
• Industrial Electronics: Deployed in process control systems and test equipment requiring low drift.
