LM113H/NOPB

Overview

The LM113H/NOPB is a precision shunt voltage reference manufactured by Texas Instruments. It provides a stable 1.22V output with a tolerance of ±5%. The device operates within a cathode current range up to 500 µA and exhibits low noise, specified at 5µVrms from 10Hz to 10kHz. Designed for through-hole mounting in a TO-99 package, it supports an extended operating temperature range from -55°C to +125°C (TA). This component serves as a reliable reference diode for applications requiring high stability and low drift.

Feature Summary

Provides a fixed 1.22V precision reference output
Features low noise performance of 5µVrms over the 10Hz to 10kHz bandwidth
Supports operation across an extended industrial temperature range

Applications

Precision analog-to-digital converter reference circuits
High-stability power supply regulation systems
Calibration equipment requiring accurate voltage standards

Procurement Notes

Verify the specific suffix H indicates the military/extended grade variant compatible with the NOPB lead-free designation. Confirm the TO-99 package style matches your PCB footprint requirements. Ensure the 1.22V output aligns with your circuit design needs. Check RoHS compliance documentation for final assembly integration. Validate the ±5% tolerance meets your system accuracy specifications before procurement.

Selection Notes

Select this component when a fixed 1.22V reference is required rather than standard 2.5V or 5V options. Consider the TO-99 through-hole package if surface-mount alternatives are unsuitable. Evaluate the ±5% tolerance against tighter precision requirements that might necessitate A-grade variants. Assess the 500 µA cathode current limit for power consumption constraints in low-power designs.

Part Context

The LM113 series belongs to Texas Instruments' family of precision reference diodes. The LM113H/NOPB specifically denotes the hermetically sealed TO-99 version with extended temperature capabilities. It complements other LM113 variants like LM113QML for aerospace applications. This part continues the legacy of stable bandgap references used in critical instrumentation and control systems.
