Product Overview
Panasonic's ECH-U is a stacked metallized PPS film chip capacitor series, and this listing is its 3300 pF rung. In this part number 1H is the 50 V DC rating, 332 is the EIA picofarad code for 3300 pF, the .0033uF printed in the name, and J is the plus or minus 5 percent tolerance code; the trailing B5 matches no published Panasonic decode table, so the part number is quoted as it stands and no meaning is invented for it. The photo of this stock is the closest crop we have of the tape: a clear carrier strip crossing the frame with pockets running out past both edges, sprocket holes along the top, and the cover tape down and catching a highlight across the middle. Each pocket holds one upright slate gray body with a lighter rim and a round dimple in the top face, and no printed capacitance or part marking is visible on any of them in this photo. Ten pieces on the shelf, sold each.
Key Features
- Capacitance: .0033uF (3300 pF), EIA code 332 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
- Filter corner-setting in analog signal chains
- Time-constant and timing networks
- Oscillation and resonance circuits
- Audio stages that want a film dielectric
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. One chip and ten chips carry the same $8, so it is worth building the cart out with the other values the board needs before checkout and letting the $28 line clear the freight.
What are the soldering limits for these? Per Panasonic's published ECH-U series data, reflow soldering is specified at 260 degrees C maximum with no more than 95 seconds above 220 degrees C, and the series is listed as RoHS compliant with no safety function. That is Panasonic's published limit for every one of the ten pieces here, not a house recommendation, so follow it rather than guessing from a neighboring part.
Three thousand three hundred picofarads that will sit in a filter for twenty years and never once ask for attention.
