MRS1K0BF

MRS1K0BF Description

The MRS1K0BF 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). This 1206 (3216 Metric) convex, long-side terminal package features isolated resistors, each with a 1kΩ resistance and an exceptional ±0.1% tolerance, ensuring minimal deviation in critical circuits. With a ±25ppm/°C TCR, it delivers superior stability across temperature variations, making it ideal for precision analog designs. The 62.5mW power rating per element and ROHS3 compliance further enhance its reliability in modern electronics.

MRS1K0BF Features

• Precision Performance: ±0.1% tolerance and ±25ppm/°C TCR for unmatched accuracy.
• Robust Construction: 1206 convex package with long-side terminals for improved mechanical stability.
• High Reliability: MSL 1 (Unlimited) moisture sensitivity and REACH unaffected status ensure longevity.
• Optimized Layout: Isolated circuit design minimizes crosstalk in voltage divider applications.
• Industry Compliance: ROHS3 compliant and EAR99/ECCN classified for global use.

MRS1K0BF Applications

The MRS1K0BF excels in precision voltage dividers, TCR-matched networks, and sensor signal conditioning, where resistance matching and thermal stability are critical. Its low TCR makes it suitable for:

• Medical instrumentation (e.g., patient monitoring systems).
• Industrial automation (e.g., bridge circuits in strain gauges).
• Test & measurement equipment requiring drift-free performance.
• Aerospace and automotive electronics where reliability under thermal stress is paramount.

Conclusion of MRS1K0BF

The MRS1K0BF stands out for its precision, stability, and ruggedness, offering engineers a dependable solution for high-accuracy analog designs. While marked obsolete, its technical merits—such as TCR matching and tight tolerance—make it a preferred choice for legacy or niche applications demanding uncompromising performance. For voltage-sensitive or thermally challenging environments, this resistor network remains a benchmark in its class.
