Based on the info you provided, this is ugly but it should work:

create table #data
(
    names varchar(50)
)

insert into #data values('type12pen105A')
insert into #data values('type12pen101A')
insert into #data values('type12pen112A')
insert into #data values('type12pen120A')
insert into #data values('type12pen110A')
insert into #data values('type12pen106A')
insert into #data values('type12pen110C')
insert into #data values('type12pen110D')
insert into #data values('type12pen110E')
insert into #data values('type12pen121B')

SELECT Names
FROM #Data
WHERE Names LIKE 'type12pen%' 
AND RIGHT(Names,1) = 'A'
AND replace(replace(names, 'type12pen', ''), 'A', '') BETWEEN 100 AND 110 

drop table #data

results:

type12pen105A
type12pen101A
type12pen110A
type12pen106A
