Product Overview
The ECH-U family is Panasonic's stacked metallized PPS film chip capacitor line, built with the film stacked and metallized rather than wound and molded, per Panasonic's published series data. On this page the 331 code reads 33 x 10 pF, which is 330 pF or .00033 uF, so the .0003 uF in the old title was a rounding of the same number and the title now carries the decoded value. Ten pieces are here, shown as one taped strip lying along the bottom of the frame with ten pockets in view, the outer two clipped by the edges, small gray bodies with a round dimple on each top face and cover tape still over them.
Key Features
- Capacitance: 330 pF, also written .00033 uF, decoded from the 331 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
- 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
- Mounting: two terminal surface mount chip, ECH-U series
- Verify against Panasonic's published ECHU(X) series data before designing in.
Applications
- Filter corner setting where the value must hold across temperature
- Time constant circuits
- Oscillation and resonance networks
- Audio stages, as published by Panasonic for this family
Frequently Asked Questions
How many should I order?
Order the number of positions on the board and let the cart do the rest. There are ten here and ten is the whole count for 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 tally 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.
Why does the code say 330 pF when the old title said .0003 uF?
Because .0003 uF is a rounding, not a real step. The 331 in ECH-U1H331JB5 decodes as 33 x 10 pF, and 33 is a standard E12 value while 30 is not, so 330 pF is the only reading this part number supports. We corrected the title and left the part number alone; if you were sourcing against .0003 uF in a bill of materials, 330 pF is the part you were looking for.
Three hundred and thirty picofarads, sitting quiet under the cover tape, waiting for a filter corner to land.
