PBV, resistors designed mounting heat sink. utilizes spring clip. Both have screw mounting capability. Etched Manganin foil copper terminals provide temperature coefficient resistance, long term stability inductance. internal thermal resistance, <4K/W, assures self-heating rating. four terminal (Kelvin) version which provides lower resistance range (0.0005 where precision measurement current necessary. ideal power electronics control applications.
