CMEJ-4618-42-L010

Overview

The CMEJ-4618-42-L010 is a compact, low-profile surface-mount electromagnetic relay manufactured by Same Sky. It features a single-pole double-throw (SPDT) switching configuration with a coil voltage of 5V DC. The device utilizes a gold-plated contact system to ensure reliable signal integrity in sensitive applications. Designed for high reliability, it offers a mechanical life of at least 10 million operations and an electrical life of 100,000 cycles under rated load conditions. The unit operates within a temperature range of -40°C to +85°C and meets UL and CUL safety standards.

Feature Summary

• Compact surface-mount design suitable for space-constrained PCB layouts
• Gold-plated contacts provide stable performance for low-level signal switching
• High operational reliability with extended mechanical and electrical life cycles
• Compliant with international safety certifications including UL and CUL

Applications

• Consumer electronics requiring low-voltage signal switching
• Industrial control systems utilizing small form-factor relays
• Automotive telematics and infotainment modules
• Medical equipment needing reliable isolated switching components

Procurement Notes

Verify the specific ordering code against the manufacturer's current datasheet to confirm pinout orientation and contact material specifications. Ensure that the selected variant matches the required coil voltage and switching capacity for your circuit design. Cross-reference safety certification marks such as UL or CUL if regulatory compliance is mandatory for your end product. Confirm package dimensions and soldering profile requirements prior to integration into the manufacturing process.

Selection Notes

Select this component when a low-profile SPDT relay is needed for 5V DC control circuits. Consider its small footprint for dense board arrangements where traditional through-hole relays are impractical. Evaluate the contact rating against the maximum load current and voltage expected in the application. Verify thermal management needs given the operating temperature range and power dissipation characteristics during continuous operation.

Part Context

This model belongs to Same Sky's series of miniature electromagnetic relays designed for surface-mount technology. The series emphasizes miniaturization without compromising switching capability or longevity. These relays are engineered to replace larger legacy components in modern electronic devices, offering improved assembly efficiency and reduced overall system volume while maintaining robust electrical performance standards.

Replacement Considerations

Check for direct cross-references from manufacturers like Omron or Panasonic with similar SPDT configurations and 5V coil ratings. Ensure physical footprint compatibility and pin alignment before substituting. Verify that alternative parts meet the same UL/CUL safety approvals and environmental operating ranges specified for the original component.
