Frequently Asked Questions
Why should I parallel a ceramic capacitor with CD11 1000uF/25V?
Aluminum electrolytic capacitors like CD11 1000uF/25V have excellent low-frequency filtering capability but higher ESL (equivalent series inductance) which limits high-frequency performance. Paralleling with a 0.1uF ceramic capacitor provides: 1) Low ESL for high-frequency noise suppression; 2) Lower impedance across a wider frequency range; 3) Better handling of switching transients from SMPS. The ceramic capacitor should be placed as close as possible to the load or switching device.
For switching power supplies, always parallel electrolytic capacitors with ceramic capacitors for optimal filtering across all frequencies.
What is the lead spacing and mounting orientation for CD11 1000uF/25V?
CD11 1000uF/25V (8x16mm) has a standard lead spacing of 3.5mm (0.138 inches). The negative terminal is identified by a colored stripe on the capacitor body and shorter lead. Proper mounting orientation: 1) Observe polarity - reverse polarity will damage the capacitor; 2) Maintain minimum 3mm clearance from PCB for 105C rated parts; 3) For vertical mounting, ensure adequate headroom (16mm height); 4) Horizontal mounting possible with formed leads.
Always verify polarity before soldering. Use polarity markings on PCB silkscreen to prevent assembly errors.
