L081S472LF

L081S472LF Description

The L081S472LF from TT Electronics/IRC is a high-reliability 7-resistor bussed network designed for precision applications. Encased in a conformal-coated SIP package, it features 4.7KΩ thick-film resistors with a tight 2% tolerance and a low ±100ppm/°C temperature coefficient. Rated for 0.8W total power dissipation (0.125W per resistor) and 100V maximum voltage, it operates across a wide temperature range (-70°C to +125°C), making it suitable for harsh environments. The 8-pin through-hole design (20.32mm length, 2.5mm width, 5.08mm height) ensures robust mechanical stability, while its bussed (BUS) circuit configuration simplifies PCB layout. Compliant with EU RoHS (with exemption) and EAR99 ECCN, it is ideal for industrial and commercial electronics.

L081S472LF Features

• High Power Handling: 0.8W total (0.125W per resistor) with derating up to 125°C.
• Stable Performance: ±100ppm/°C TCR ensures minimal resistance drift.
• Durable Construction: Conformal coating protects against moisture and contaminants.
• Space-Efficient: SIP package (2.54mm pitch) saves board space vs. discrete resistors.
• Broad Compatibility: Through-hole mounting suits automated assembly processes.
• Reliable Bussed Design: Single common terminal (BUS) reduces wiring complexity.

L081S472LF Applications

• Power Supplies: Voltage divider networks and load balancing.
• Industrial Controls: Signal conditioning in PLCs and motor drives.
• Automotive Electronics: Non-AECQ-rated but suitable for non-safety-critical systems.
• Test & Measurement Equipment: Precision reference circuits.
• Consumer Electronics: Audio amplifiers and display drivers.

Conclusion of L081S472LF

The L081S472LF excels in high-density, high-reliability designs requiring stable resistance networks. Its thick-film technology, conformal coating, and bussed architecture offer superior performance over discrete resistors in space-constrained or harsh environments. While not PPAP or automotive-grade, it is a cost-effective solution for industrial, commercial, and instrumentation applications demanding precision and durability. Bulk packaging ensures scalability for volume production.
