Inductance: 10μH~22μH (EAS30S), 10μH×2~22μH×2 (EAW30S)
• High sound quality, low distortion, and low heat generation
• EAS30S: 1coil in 1unit structure and EAW30S: 2 coils in
• A magnetically shielded structure prevents radiation noise
• RoHS compliant
TYPE EAS30S (1coil in 1unit)
TYPE EAW30S (2coils in 1unit)
(1) Inductance is measured with a LCR meter 4284A* or equivalent.
(2) DC Resistance is measured with a Digital Multimeter TR6871
(3) Inductance decrease current based upon 10% inductance
(4) Temperature rise current based upon 40°C temperature rise.
