*1 Temperature on the coil surface including the temperature rise
in installation. Never use the coil at a temperature exceeding the
rated temperature range.
*2 Recommended range. When infra-acoustic frequency component
is impressed, a beat sound sometimes occurs.
*3 The temperature rise on the coil surface at the rated d.c. current.
*4 Housing case material.
