Product Overview
Panasonic titles this family the stacked metallized PPS film chip capacitor, ECHU(X) series, and publishes it at 16 V and 50 V with a category range of -55 to +125 degC. This one is the 471 code, 47 x 10 pF, so 470 pF or .00047 uF at 50 V, which is what the existing title already said and what we kept. Ten pieces sit here, photographed as a single strip of carrier tape running across the upper part of the frame with ten pockets in view, gray bodies with a shallow round dimple on the top face, a corner of a clear poly bag at the lower right and a pen tip below for scale.
Key Features
- Capacitance: 470 pF, also written .00047 uF, decoded from the 471 EIA code in the part number
- Voltage: 50 V DC, from the 1H code, per Panasonic's published ECHU(X) decode
- Tolerance: +/-5%, from the J code, per Panasonic's published tolerance codes (G is +/-2%, J is +/-5%)
- Dielectric: stacked metallized PPS film, mold-less construction, per Panasonic's published ECHU(X) data
- Operating range: -55 to +125 degC including temperature rise at the unit surface, per published ECHU(X) data
- Dissipation factor: tan d 0.6% max at 20 degC and 1 kHz, per published ECHU(X) data
- Insulation resistance: 3000 Mohm min at 50 V, 20 degC, 60 s, per published ECHU(X) data
- Endurance: 85 degC, 85% RH at working voltage for 500 hours, per published ECHU(X) data
- Reflow: 260 degC max, 95 s max above 220 degC, RoHS compliant, no safety function, per published ECHU(X) data
- Case size: not stated here. Panasonic's current ECHU(X) tables decode X5 and X9 suffixes, and no published table decodes the B5 on this part number
- Verify against Panasonic's published ECHU(X) series data before designing in.
Applications
- Timing and time constant networks
- Filter stages in signal paths
- Oscillation and resonance circuits
- Audio circuit positions, as published by Panasonic for this family
Frequently Asked Questions
How many should I order?
Order the count the build needs, plus a spare or two if the board has more than a couple of these positions. Ten is the exact number on the shelf at this listing. The photo takes in ten pockets, but the tape runs past both edges of the frame, so read it as a picture of the stock rather than a count of it. Shipping is $8 flat rate and free on orders over $28, so small parts like this ship smartest as part of a larger order.
Can I identify these once they are off the tape?
Plan on labelling them yourself. The top faces in this photo read plain gray with a shallow round dimple in the middle and no printed value visible, which is normal for a stacked film chip and means a loose part on the bench cannot be told from its neighbour by eye. Label them yourself as soon as they are loose, and measure before placing if a few values have already been mixed.
Four hundred and seventy picofarads is a quiet number in a timing network, and this is a quiet part to match.
