簡(jiǎn)介：Oxford Electrical Products was established in 1982 and quickly became one of the UK's leading and most highly respected wound component manufacturers. OEP has always been renowned for its audio, pulse, line isolating and mains transformer ranges but over the years the ranges and product offerings, along with the customer base, has expanded rapidly to embrace switch-mode, toroidal, SMDs, flyback, digital transformers and many other standard or customer specific products.
描述:
OEP A187A10C Audio Input Transformers A187A10C audio input transformers from OEP have multiple electrostatic and magnetic shields and provide galvanic isolation. The A187A10C transformer is a high ratio step down transformer featuring Faraday shielding that reduces hum and stray magnetic interference. +21.5dbu maximum input level at 20 Hz with >1% distortion 250 Vrms proof voltage from winding to winding and screens to winding 155 mH primary leakage inductance at 1 kHz 42 pF interwinding capacitance at 1 kHz for primary to secondary 1 63 pF interwinding capacitance at 1 kHz for primary to secondary 2 39 pF interwinding capacitance at 1 kHz for primary to shield ### Product Application Information These audio input transformers are suitable for long cable runs without HF loss. They can be used for coupling instrument pickups to low impedance microphone inputs and unbalanced line level to balanced microphone outputs. ### 注 Do not pass DC through the windings. ### 印刷電路板和機(jī)架安裝

OEP A187A12C Audio Input Transformers A187A12C audio input transformers from OEP provide galvanic isolation and are constructed with multiple electrostatic and magnetic shields. They feature a low distortion core and reduce the audio hum and buzz between the ground at the send and receive terminations of the signal. Proof voltage of 250 Vrms from windings to screen and from primary to secondary 140 pF interwinding capacitance at 20 Hz (primary to screens and secondary to screens) 1.2 mH primary leakage inductance at 1 kHz 2.82 H nominal inductance for each winding ### Product Application Information Suitable applications include ground loop elimination, high common mode rejection and dual electrostatic shields. Another use for these audio transformers is unbalanced line level to balanced microphone outputs. ### 注 Do not pass DC through the windings. ### 印刷電路板和機(jī)架安裝
