L101S152LF

L101S152LF Description

The L101S152LF from TT Electronics/IRC is a high-reliability thick-film bussed resistor network designed for precision applications. Encased in a conformal-coated SIP (Single In-Line Package), it integrates nine 1.5 kΩ resistors with a 2% tolerance and a ±100ppm/°C temperature coefficient. Rated for 1W total power dissipation (0.125W per resistor) and 100V maximum voltage, it operates across a wide temperature range (-70°C to +125°C). The 10-pin through-hole design with a 2.54mm pitch ensures robust mechanical stability, while its RoHS-compliant (with exemption) construction meets environmental standards.

L101S152LF Features

• Bussed Circuit Design: Simplifies PCB layout by connecting resistors in a common bus configuration, reducing wiring complexity.
• High Power Handling: 1W total rating (1/8W per resistor) with derated performance up to 125°C.
• Conformal Coating: Enhances durability against moisture, dust, and chemical exposure, ideal for harsh environments.
• Thick-Film Technology: Delivers stable resistance values with low noise and high repeatability.
• Compact SIP Package: 25.4mm length × 2.5mm width × 5.08mm height, saving board space while supporting through-hole mounting.
• Automotive-Grade Alternatives: While not PPAP-certified, its rugged design suits industrial and telecom applications.

L101S152LF Applications

• Power Supply Modules: Voltage division and current limiting in DC/DC converters.
• Industrial Controls: Signal conditioning and pull-up/down networks in PLCs and sensors.
• Telecommunications: Impedance matching and termination in RF and baseband circuits.
• Test & Measurement Equipment: Precision reference networks due to low TCR (±100ppm/°C).
• Aerospace & Defense: Conformal coating ensures reliability in high-vibration environments.

Conclusion of L101S152LF
