Product Overview
Panasonic's ECU-V line is a general usage surface mount multilayer ceramic family that published parts data lists as obsolete. These twenty-nine pieces are still on white paper carrier tape: the close frame shows three seated in their pockets, dark maroon bodies with silver end terminations and nothing printed on the ceramic, and the wider frame shows three separate tape runs, one lying flat with seven pockets filled and two more crossing beneath it at an angle. Twenty-nine is the count on the shelf here, and no single frame in these photos holds all of them.
Key Features
- Capacitance: 39 pF, from this listing's own name and part number
- Voltage: 50 V DC (1H voltage code, per Panasonic's ECU series catalog)
- Tolerance: +/-5% (J code, per Panasonic's ECU series catalog)
- Temperature characteristic: C0G, 0 +/-30 ppm/degC (C code, per the same catalog)
- Mounting: surface mount, two terminals, reflow, per published ECU series data
- Operating range: -55 to +125 degC, per published ECU series data for this family
- Series: Panasonic (Matsushita) ECU-V general usage multilayer ceramic chip capacitor
- Case size is not confirmed in published data for this part number, so we do not state one
- Verify against Panasonic's published ECU series data before designing in.
Applications
- RF tuning and impedance matching networks
- Oscillator and timing circuits that need a stable small value
- Coupling and filter positions on legacy surface mount boards
- Like-for-like replacement during board repair
Frequently Asked Questions
How many should I order?
Twenty-nine is our count on this value, so a bench run and a handful of spares both fit inside one order. These photos show the tape already in three separate lengths rather than on one continuous reel, so a partial count comes off what you see here. Even the full twenty-nine is a light order on its own. Shipping is $8 flat rate and free on orders over $28, so small parts like this ship smartest as part of a larger order.
What does the J in ECUV1H390JCM mean?
Per Panasonic's ECU series catalog, J is the tolerance code for +/-5% and the C after it is the C0G temperature characteristic. None of that is printed on the bodies in these photos, so the carrier tape is the only thing here that identifies the value; keep them in it until they go down on the board.
Thirty-nine picofarads is a small thing to be missing and a smaller thing to fix.
