L103S102LF

L103S102LF Description

The L103S102LF from TT Electronics/IRC is a high-reliability thick-film resistor network designed for precision applications requiring stable performance in demanding environments. This 10-pin SIP (Single In-Line Package) device features five isolated 1 kΩ resistors with a 2% tolerance and a ±100ppm/°C temperature coefficient, ensuring consistent operation across a wide temperature range of -55°C to +125°C. Conformal coated for enhanced durability, it offers a 1W total power rating (0.2W per resistor) and a 100V maximum voltage rating, making it suitable for industrial and automotive-grade circuits. The through-hole pin termination and 2.54mm pitch facilitate easy PCB integration.

L103S102LF Features

• Isolated Circuit Design (ISOL): Each resistor operates independently, eliminating crosstalk in multi-channel applications.
• Conformal Coating: Protects against moisture, dust, and chemical exposure, ideal for harsh environments.
• High Power Handling: 1W total dissipation (0.2W per resistor) at 70°C, derated linearly to 125°C.
• Low TCR (±100ppm/°C): Minimizes resistance drift under thermal stress.
• RoHS Compliant (with Exemption): Meets environmental standards while maintaining performance.
• Bulk Packaging: Cost-effective for high-volume production.
