Panasonic ERJ-3EKF1004V Resistor: Specifications and Procurement Guide

Electronic systems used in aviation, defense, industrial controls, and other demanding applications require precisely specified components for reliable circuit performance. The Panasonic ERJ-3EKF1004V is a precision thick-film chip resistor designed for compact surface-mount applications. It is associated with NSN 5905-01-537-5997, providing an additional procurement reference for organizations working with NSN-based inventory systems.

Panasonic ERJ-3EKF1004V Overview

The ERJ-3EKF1004V belongs to Panasonic's general-purpose precision thick-film chip resistor family. According to Panasonic's published specifications, the component has a 1 MΩ resistance value, ±1% resistance tolerance, and a 0.1 W power rating. Its compact 1.6 × 0.8 mm package corresponds to the EIA 0603 size.

The component also features a temperature coefficient of resistance (TCR) of ±100 ppm/°C. These specifications make it suitable for circuit designs where controlled resistance, compact dimensions, and consistent electrical performance are important.

Understanding NSN 5905-01-537-5997

NSN 5905-01-537-5997 identifies a resistor component within the Federal Supply Classification system. NSN-based identification can help procurement teams distinguish a required component from similar-looking commercial parts and organize purchasing, inventory, and maintenance requirements.

For buyers, however, an NSN should not replace technical verification. Part number, manufacturer, resistance, tolerance, package size, and applicable specifications should be checked against the equipment's approved documentation before procurement.

Applications and Selection Considerations

Chip resistors are fundamental passive components used for functions such as current limiting, voltage division, signal conditioning, and biasing. Panasonic's technical application materials also demonstrate the broader role of chip resistors in precision voltage-measurement and control circuits.

When selecting the ERJ-3EKF1004V or an equivalent component, engineers and procurement professionals should verify:

1. Required resistance and tolerance.
2. Circuit power dissipation.
3. Physical package and PCB footprint.
4. Temperature coefficient requirements.
5. Environmental and qualification requirements.
6. Manufacturer and exact part-number compatibility.

Sourcing Panasonic Components

Reliable sourcing is particularly important for aerospace, defense, and industrial maintenance programs where incorrect substitutions can create compatibility or documentation issues. Buyers should verify manufacturer information, exact part numbers, specifications, and traceability before placing an order.
