Product Overview
Panasonic's ECH-U is a stacked metallized PPS film chip capacitor series, and this listing is its 22,000 pF rung. In this part number 1H is the 50 V DC rating, 223 is the EIA picofarad code for 22,000 pF, and J is the plus or minus 5 percent tolerance code, so the name and the part number agree; the trailing B5 has no published decode and gets none here. Panasonic publishes the 50 V capacitance range for the series as running to 0.10 uF, so .022uF sits inside it with room above. Our stock is a cut length of clear carrier tape on a white sheet over a green mat: eight full pockets in frame, sprocket row along the top, cover tape down, and the squared cut end of the strip at the right with a wisp of cover tape curled across the last body. The bodies photograph as squarish charcoal gray blocks with a bright round depression in the top face, and no printed capacitance or part marking is visible on them in this photo. Ten pieces on the shelf, sold each.
Key Features
- Capacitance: .022uF (22,000 pF), EIA code 223 per Panasonic's published ECH-U decoding
- Capacitance tolerance: plus or minus 5 percent, the J code in Panasonic's published ECH-U tolerance table, where G is the plus or minus 2 percent code
- Rated voltage: 50 V DC, the 1H code per Panasonic's published ECH-U data
- Dielectric: stacked metallized PPS film, mold-less construction, per Panasonic's published ECH-U (ECHU(X)) series data
- Category temperature range: minus 55 to plus 125 degrees C, per Panasonic's published ECH-U series data
- Dissipation factor: tan d 0.6 percent or less at 20 degrees C and 1 kHz, per Panasonic's published ECH-U series data
- Insulation resistance: 3000 megohms or more, measured at 20 degrees C, 50 V, 60 seconds, per Panasonic's published ECH-U series data
- Withstand voltage between terminals: rated voltage times 150 percent for 60 seconds, per Panasonic's published ECH-U series data
- Mounting: surface-mount chip; Panasonic publishes reflow at 260 degrees C maximum, 95 seconds maximum above 220 degrees C, and lists the series RoHS compliant with no safety function
- Series: Panasonic ECH-U; no Panasonic table we can cite decodes the trailing B5, so we assign it no meaning
- Stock on hand: ten pieces, sold each
- Verify against Panasonic's published ECH-U series data before designing in.
Applications
- Audio filter and tone networks
- Time-constant circuits
- Filtering on low-voltage analog boards
- Oscillation and resonance circuits
Frequently Asked Questions
How many should I order? Ten pieces of this capacitance code are on the shelf and they sell each, so ten is the ceiling on today's order. Shipping is $8 flat rate and free on orders over $28, so small parts like this ship smartest as part of a larger order. If the rest of the cart is already past $28 these ride along free, and if it is not, the $8 is the same whether you take one of these or all ten.
What does the B5 at the end of the part number mean? We do not know, and we will not guess. Panasonic's current published ECHU(X) datasheet uses X5 and X9 suffixes, and no published table decodes B5, so we list the part number exactly as it stands and decode only the portions Panasonic publishes. If that suffix has to match an approved-vendor list on your end, ask us before ordering rather than after.
Twenty-two nanofarads with a film dielectric, the kind of part that makes an audio board sound the way the schematic promised.
