RCD offers a wide range of SM and thru-hole capacitors including standard and specialty ceramic, tantalum, hi-volt, low ESR, networks, etc. Fill in as much info as you canand send to or fax (603) 669-5455.
1. Is this an existing or new application? If existing, what parts are you using now?:Mfr
Model: description: Are there any problems or deficiencies with the existing parts that you'd like RCD to improve upon? (please describe)
If a new application, have you found parts made by any other firm that are working OK, or seem promising? If so, please list Mfr: Model: Description:
2. Application: Energy Storage Discharge Filtering AC Application Other
3. Capacitance value: Tolerance: Voltage Rating:
Construction: Tantalum, Ceramic NPO/COG X7R X5R Y5V/Z5U , Other:
Maximum ambient temperature: Forced air cooling?: Yes or No
Frequency: Worst Case voltage across capacitor: DC AC
Worst case Peak-to-Peak voltage across capacitor:
Voltage Reversal: Normal Fault
Ringing Frequency: Normal Fault
RMS Current: Peak Current: Normal Fault
Duty Cycle: Continuous Mode: Burst Mode: On/Off Time:
4.Pulse Applications Only
Charge time: Hold Time: Discharge Time: Repetition rate:
If feasible, include a scope plot of the worst case amplitude. For sine or near sine wave applications, one complete period is sufficient. For pulse applications; show each voltage transition in detail across at least 2 horizontal divisions as well as onecomplete period. This may require a separate waveform plot for each transition.Ensure all waveforms include the zero voltage reference, vertical sensitivity, and time scale. RCD recommends not using vertical amplifier bandwidth limiters when examining fast voltage transitions, since this can hide fasttransients and create rise time errors.Voltage measurements should be used for application analysis, since current measurements tend to addinductance. RMS current is essentially meaningless for pulse applications due to lack of frequency info.If applicable describe application circuit or send circuit diagram.
