RMKMS408-50KBWT

RMKMS408-50KBWT Description

The RMKMS408-50KBWT from Vishay is a high-precision, surface-mount thin-film resistor network designed for demanding applications requiring tight tolerance and low temperature coefficient. This 8-pin SO (Small Outline) package features four isolated 50 kΩ resistors with a tolerance of ±0.1% and a temperature coefficient of ±10 ppm/°C (standard) or ±15 ppm/°C, ensuring exceptional stability across a wide operating range of -55°C to +125°C. The molded case style and gull-wing termination provide robust mechanical and electrical performance, making it suitable for automated assembly processes. With a 0.25W (1/4W) total power rating and 50V maximum voltage rating, this network is ideal for precision analog and digital circuits.

RMKMS408-50KBWT Features

• Precision Performance: Ultra-tight ±0.1% tolerance and low ±10/±15 ppm/°C TCR for minimal drift.
• Isolated Resistors: Four independent 50 kΩ resistors (ISOL design) for flexible circuit design.
• Robust Construction: Molded SO package with gull-wing leads for reliable surface-mount attachment.
• High Power Handling: 0.05W per resistor (0.25W total) and 50V rating for stable operation.
• Automation-Friendly: Supplied in tape and reel (T/R) packaging for efficient PCB assembly.
• Wide Temperature Range: Operates from -55°C to +125°C, derated up to 125°C.
• Compliance: EU RoHS compliant and EAR99 (ECCN) for global use.

RMKMS408-50KBWT Applications

This resistor network excels in precision applications such as:

• Medical Devices: Patient monitoring equipment requiring stable signal conditioning.
• Industrial Automation: High-accuracy sensor interfaces and control systems.
• Test & Measurement: Calibration circuits and instrumentation amplifiers.
• Communications: RF and signal processing where low drift is critical.
• Automotive (Non-Automotive Rated): Infotainment and ADAS subsystems (note: not PPAP/automotive certified).
