Product Overview
Panasonic's published ECHU(X) data covers .00010 uF through .10 uF at 50 V in this stacked metallized PPS film chip family. This listing is the 472 code, 47 x 100 pF, so 4700 pF or .0047 uF, matching the value the title already carried; the J in the part number is the +/-5% tolerance letter, which is worth noting because the old feature list on this page said +2%, and +/-2% is the G code. Ten pieces are on the shelf, photographed as one tape strip sealed inside a clear poly bag, seven pockets in the frame with the rightmost clipped, gray bodies with a round dimple on the top face and bag creases throwing bright highlights across the picture.
Key Features
- Capacitance: 4700 pF, also written .0047 uF, decoded from the 472 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
- Withstand voltage between terminals: rated voltage x 150% for 60 s, 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
- Audio circuit coupling and shaping, as published by Panasonic for this family
- Filter networks in the low kilohertz region
- Time constant circuits
- Oscillation and resonance stages
Frequently Asked Questions
How many should I order?
Order the count the board calls for. Ten is what this listing holds, all of it, and the seven you can count in the frame are part of that same strip rather than a separate lot. A stereo pair or a matched filter section fits inside that count several times over. 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 ECH-U1H472JB5 mean?
It is the capacitance tolerance letter. Panasonic's published ECHU(X) tolerance codes give G as +/-2% and J as +/-5%, so this part is a +/-5% piece. The older feature text on this page quoted +2%, which belongs to a G part number, and the part number is the authority here. If a design needs +/-2%, look for the G letter in the same position rather than ordering these.
Forty-seven hundred picofarads, small enough to lose in a fold of the bag it is photographed in.
