Here is a typical table from a DC E2H 5V-to-5V isolated datasheet:
| Parameter | Conditions | Min | Typ | Max | Unit | | :--- | :--- | :--- | :--- | :--- | :--- | | Output Voltage | V_in = 5V, Load = 100% | 4.85 | 5.00 | 5.15 | V | | Output Ripple & Noise | 20 MHz BW | – | 50 | 100 | mV p-p | | Line Regulation | V_in min to max | – | 0.5 | 1.2 | % | | Load Regulation | 10% to 100% load | – | 1.0 | 2.0 | % | | Isolation Capacitance | 100kHz, 0.5V | – | 20 | – | pF | | Switching Frequency | – | 50 | 100 | 150 | kHz |
What to Watch:
Q1: Can I use the DC E2H in parallel to get more current? dc e2h datasheet
Q2: What is the mean time between failures (MTBF)?
Q3: How do I test if my DC E2H is genuine?
Q4: Does the datasheet cover EMC emissions? Here is a typical table from a DC
When reading the datasheet, focus on these critical sections to ensure it works with your system:
Because "DC E2H" is a generic descriptor, many manufacturers offer equivalents. Always trust the datasheet, not the marketing title.
| Manufacturer | Equivalent Series | Key Difference | | :--- | :--- | :--- | | Murata | NTE Series | Higher isolation (6kV) | | Recom | RECOM RxxPxx | Lower profile (6.7mm) | | XP Power | IA Series | Wide input range (2:1) | | CUI Inc. | PBO-1 Series | Lower ripple (30mV p-p) | Q2: What is the mean time between failures (MTBF)
Pro Tip: Download the official datasheet from the manufacturer’s website, not a third-party aggregator. Revision numbers matter. A "Rev B" DC E2H datasheet may have corrected thermal data compared to "Rev A."
Scenario: You need to power an isolated CAN transceiver (5V, 100mA) from a 24V industrial bus. You select a DC E2H-24S05 (hypothetical 24V input variant).
