Aluminum Capacitors
Axial Standard Miniature
FEATURESS
• Polarized aluminum electrolytic capacitors,
non-solid electrolyte
• Axial leads, cylindrical aluminum case,
insulated with a blue sleeve
• Mounting ring version not available in insulated form
• Taped versions up to case Ø 15 x 30 mm available for
automatic insertion
• Charge and discharge proof
• Miniaturized, high CV-product per unit volume
• Lead (Pb)-free versions are RoHS compliant
APPLICATIONS
• General purpose, industrial, automotive, audio-video
• Coupling, decoupling, smoothing, filtering, buffering
• Portable and mobile equipment (small size, low mass)
• Low mounting height boards, vibration and shock resistant
MARKING
The capacitors are marked (where possible) with the
following information:
• Rated capacitance (in µF)
• Tolerance on rated capacitance, code letter in accordance
with IEC 60062 (M for ± 20 %)
• Rated voltage (in V)
• Upper category temperature (85 °C)
• Date code in accordance with IEC 60062
• Code for factory of origin
• Name of manufacturer
• Band to indicate the negative terminal
• “+” sign to identify the positive terminal
(not for case sizes L < 18 mm)
• Series number (021)
