NJM432SF-TE1

Overview

The NJM432SF-TE1 is an adjustable shunt precision voltage reference IC manufactured by Nisshinbo Micro Devices. It operates within a supply voltage range of up to 36V and provides an output voltage adjustable from 2.495V to 37V. The device features an initial accuracy of 1.8% and supports a maximum shunt current of 100mA with a minimum operating current of 700µA. It is housed in a compact SC-74A (SOT-753) surface-mount package and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Adjustable output voltage configuration for variable power supply applications
• High precision performance with low initial tolerance
• Compact surface-mount packaging for space-constrained designs

Applications

• Variable output power supplies
• Precision voltage regulation circuits
• Portable electronic devices requiring stable reference voltages

Procurement Notes

Verify the specific suffix TE1 to confirm tape-and-reel packaging and quantity specifications. Ensure compatibility with SC-74A footprints during PCB layout. Confirm RoHS compliance status through official manufacturer documentation prior to integration into regulated products.

Selection Notes

Select this component when an adjustable shunt reference is required in a small SOT-753 package. Consider the 1.8% initial accuracy and 36V maximum input voltage limits. Evaluate thermal management needs for the specified operating temperature range of -40°C to +85°C.

Part Context

This part belongs to the NJM43xS series of shunt adjustable precision references from Nisshinbo Micro Devices. It serves as a compact alternative to larger packages while maintaining precision reference capabilities. The series is designed for general-purpose power management applications requiring stable voltage references.

Replacement Considerations

The NJM432SU-TE1 is a related variant in the same family, utilizing an SOT-89-3 package instead of SC-74A. Verify pinout compatibility and physical footprint differences before substitution.
