In the world of industrial automation, power supply conversion, and embedded systems, component reliability is non-negotiable. Among the myriad of passive and active components, the DC E2H series (often associated with DC-DC converters or specific high-reliability relays, depending on the manufacturer variant) has emerged as a critical component for engineers requiring stable voltage regulation and signal isolation.
However, finding a clear, actionable breakdown of the dc e2h datasheet can be challenging. Manufacturers often provide dense PDFs filled with electrical characteristics, thermal ratings, and mechanical drawings, but they rarely explain what these numbers mean for your specific application.
This article serves as a complete walkthrough of the DC E2H datasheet. Whether you are designing a telecom power system, an automotive ECU, or an industrial sensor network, understanding this datasheet is the first step to a successful PCB layout.
| Metric | Value | |-----------------------------|---------------------------| | Cut-through latency (PTP sync)| 280 ns (port to PCIe) | | Store-and-forward latency | 450 ns (1500B frame) | | RoCEv2 send latency (4KB) | 0.9 µs (with inline write)| | Max packet rate (64B) | 500 Mpps (dual port 400G) | | PFC pause reaction time | < 2 µs | dc e2h datasheet
The generic "DC E2H" is rarely a single part number. Look for the full ordering code in the datasheet:
| Order Code | Input Voltage | Output Voltage | Output Current | Efficiency | | :--- | :--- | :--- | :--- | :--- | | DC E2H-05S05 | 4.5-5.5V | 5V | 200mA | 78% | | DC E2H-12S12 | 10.8-13.2V | 12V | 83mA | 80% | | DC E2H-05D12 | 4.5-5.5V | ±12V | ±42mA | 75% |
Selection Checklist:
| Parameter | Typical Specification | |----------------------------|----------------------------------------------------| | Host Bus | PCIe 5.0 x16 (backward compatible to 4.0/3.0) | | Max Bandwidth (PCIe) | 64 GB/s (x16 @ Gen5) bidirectional | | Atomic Operations | 32/64-bit compare-and-swap, fetch-and-add | | Address Translation Cache | 2048 entries (ATC for IOMMU) | | MSI-X Vectors | Up to 2048 | | Page Sizes Supported | 4KB, 2MB, 1GB |
Deep Note – The E2H must manage PCIe TLP (Transaction Layer Packet) ordering vs. Ethernet packet reordering. It implements a reorder buffer (depth ~512 packets) and a completion coalescing engine to reduce PCIe overhead.
The "DC E2H" usually has a cable coming out of the back. The datasheet will provide a color code. A typical Autonics pinout looks like this: In the world of industrial automation, power supply
| Wire Color | Function (Typical) | | :--- | :--- | | Brown | Power (+V) | | Blue | Ground (0V) | | Black | Phase A (Output) | | White | Phase B (Output) | | Orange | Phase Z (Zero/Index pulse) | | Others | Inverse signals (for Line Driver types) |
Note: ALWAYS check the specific pinout on the specific datasheet version you have, as manufacturers can change wire colors.
The DC E2H is a high-efficiency, DC-DC converter module designed for a wide range of applications, including industrial, automotive, and consumer electronics. This module is engineered to provide a stable and efficient power supply, converting a DC input voltage to a regulated DC output voltage. In the world of industrial automation
