Preferred name: | 
tangent of loss angle |

Synonymous name: |

Symbol: | 
tan δ} |

Synonymous symbol: | 
|

Short name: | 
tanδ |

Definition: | 
tangent of the loss angle of a capacitor at specified frequency and at reference conditions |

Note: | 
The tangent of the loss angle is equal to the equivalent series resistance divided by the capacitive reactance. |

Remark: | 
(IEC 60418-3(III.9) (1976)): The rotor should be set at minimum and maximum positions for the tan delta test on variable capacitors. IEC requires the voltage to be specified. N.B. Reciprocal of tan delta is quality factor Q. |
