Product Overview
The ECU-V line is Panasonic's general usage multilayer ceramic chip series, listed obsolete in published parts data. In the close frame three pockets sit across the picture with the sprocket holes above them, the bodies a dark brown with bright silver end bands, and a crumpled wisp of the bag film lying over the leftmost part. The wider frame shows the strip inside a clear bag on a green cutting mat, nine filled pockets in view with a crease in the bag film running across the tape and the strip leaving the picture at the right. Ten is the shelf count for this part number, they sell one at a time, and no single frame here takes in all ten.
Key Features
- Capacitance: 47 pF, from this listing's own name and the 470 capacitance code
- Voltage: 50 V DC (1H voltage code, per Panasonic's published ECU series data)
- Tolerance: +/-5% (J code, per Panasonic's published ECU series data), a band of 44.65 pF to 49.35 pF
- Temperature characteristic: C0G, 0 +/-30 ppm/degC (C code, per the same published data)
- Package: surface mount chip, two terminals, reflow, per published ECU series data
- Operating temperature: -55 degC to +125 degC, per published ECU series data for this family
- Series: Panasonic (Matsushita) ECU-V general usage multilayer ceramic chip capacitor, lifecycle listed obsolete in published parts data
- Case size is not confirmed in published data for this part number, and the trailing M is not covered by any published table, so we state neither
- Verify against Panasonic's published ECU series data before designing in.
Applications
- Crystal load capacitance either side of an oscillator
- RF filter and matching sections
- Compensation around fast op amps
- Timing legs that should not wander with temperature
Frequently Asked Questions
How many should I order?
Order the count the build needs. Ten of this part number sit on the shelf, sold one at a time rather than as a pack, which is enough for a couple of oscillator positions and spares in one 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.
What do the letters JCM tell me about drift?
Two of the three are readable from published data. Per Panasonic's published ECU series data, J is the +/-5% tolerance code, which on 47 pF is 44.65 pF to 49.35 pF, and C is the C0G temperature characteristic, specified at 0 +/-30 ppm/degC across the family's published -55 degC to +125 degC range. That combination is the reason to pick this 47 pF over a general purpose part when the value has to stay where you put it. The trailing M is where the published tables stop; nothing we could find maps it to a case size, packaging or termination, so we leave it alone.
Forty-seven picofarads specified to still be near enough forty-seven once the enclosure warms up.
