Product Overview
Panasonic describes the ECH-U construction as stacked metallized PPS film with a simple mold-less build, published from -55 to +125 degC. On this page the 473 code reads 47 x 1000 pF, which is 47000 pF or .047 uF, agreeing with the title as it stood, and the J letter in the part number is the +/-5% tolerance code rather than the +2% the old feature list claimed. Ten pieces are here, shown as one taped strip inside a clear poly bag on a green cutting mat, seven pockets in frame with the leftmost clipped, six bodies reading gray with a round top dimple and one photographing pale cream with a mottled texture; printed lettering behind the tape is not legible in this photo.
Key Features
- Capacitance: .047 uF, also written 47000 pF or 47 nF, decoded from the 473 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 B9 on this part number
- Verify against Panasonic's published ECHU(X) series data before designing in.
Applications
- Audio coupling and tone shaping, as published by Panasonic for this family
- Filter stages where a .047 uF film part replaces a ceramic
- Time constant networks
- Oscillation and resonance circuits
Frequently Asked Questions
How many should I order?
Order the count the build needs. Ten is the number on the shelf here, and the seven visible in the frame come out of that same bagged strip, so there is no reel behind the picture. Repair work usually takes one or two; a small run takes the rest. Shipping is $8 flat rate and free on orders over $28, so small parts like this ship smartest as part of a larger order.
Will these take a normal reflow profile?
Panasonic's published ECHU(X) data gives 260 degC maximum for reflow soldering with no more than 95 seconds above 220 degC, and lists the family as RoHS compliant with no safety function. Those are the published limits for the series, so a standard lead-free profile inside them is the target. Hand soldering is workable on a part this size with a fine tip, but keep the iron brief and off the body.
One of the seven in this frame photographs cream instead of gray, which is the sort of detail a picture gives you and a data sheet never will.
