Aluminum Capacitors
Axial Standard Miniature
FEATURES
• 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
∅ 15 × 30 mm available for automatic insertion
• Charge and discharge proof
•
Miniaturized, high CV-product per unit volume.
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 µ F).
• 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).
