Procurement Notes

Verify the specific suffix designation against official Lumex documentation to confirm exact pinout and electrical characteristics, as variations may exist within the product family. Ensure compliance with RoHS3 requirements if restricted substances are a constraint for the target application. Confirm that the 16-DIP through-hole package aligns with the printed circuit board layout and assembly processes. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability of the components.

Selection Notes

Select this component when multiple isolated channels are required within a single package footprint. The 5000 Vrms isolation rating makes it suitable for high-voltage separation tasks. Consider the 50mA output current capacity to ensure compatibility with downstream logic or driver circuits. The wide temperature range supports operation in harsh industrial conditions. Evaluate the 16-DIP form factor against available board space and manufacturing capabilities for through-hole assembly.

Part Context

The OCP-PCT4116/E belongs to Lumex's line of optoelectronic isolation devices, specifically designed for quad-channel applications. It serves as a solution for electrically isolating signals between different voltage domains. The device integrates four independent optical couplers within a single dual-in-line package, offering a compact alternative to discrete solutions. This integration reduces board space and simplifies assembly compared to using individual single-channel optocouplers.
